Who says you don't need arms to bike? Actually, no one says that. But the sport of bike boxing is just getting started.

During the Dubai tour, rider Andrey Grivko was disqualified after he punched fellow-rider Marcel Kittle in the head in the middle of the race. That's one way to get this done. Or you could just ride a little faster.

As you can see from the picture, he cracked him wide open, but it didn't really help in the long run.

At first Marcel seemed rightfully peeved:

I won't accept an apology for this. That has nothing to do with cycling. What Grivko did is a shame for our beautiful sport. pic.twitter.com/vvMN5LzQN0

Mario Licato got punched in the face and knocked out for looking like Shia LaBeouf. No one knows what the motivation behind it was exactly, but according to Licato's Instagram post about his black eye, the last thing he heard before going down was, "this happened bc you look exactly like Shia LaBeouf".

The story isn't all bad, it seems like Licato is recovering quickly and he even got a voicemail from Shia LaBeouf himself. Licato told Cosmopolitan what the voicemail said and it's about what you might expect a rambling voicemail from Shia LaBeouf to sound like:

Hey, this is Shia LaBeouf … I just read an article that you were punched in the face because you look like me?" And he was like, "Aw, man. That sucks. I'm so sorry. But I get it. It's happened to me before." And then he was like, "I don't know. I wish I was in New York. I'd come bring you soup." He was just like, "This sucks. I don't even know what to say. I'm sorry. People are just crazy. Just because you look like me?" I was obviously laughing the whole time. And then he was like, "Here's my phone number. Don't give it to anybody. Please, please, call me back. Call me back if you want to. We could chat. Let's giggle over this. Maybe there's a silver lining in all this. But call me back." And then he was like, "And once again, this is Shia LaBeouf, the guy you got hit for looking like. And yeah, man, I'm sorry. I'm just really sorry." And he was like "Keep your head up, G." And that was it.
